We have a lot of data in our Matomo instance from websites that have not been actively tracked for a long time. The reports for this are suddenly no longer available, but they are still available in the database in the reports table.
If you want to look at the reports of such a page, you will always get the message “No data has been recorded yet, get set up below”. As if data has never been tracked before.
If the tracking for an old website ID is temporarily restarted, all historical data for this ID is visible again.
Is that a bug?
We have version 3.13.1.
